Water molecules dont necessarily dissolve in water. Because water is a polar molecule, it has a slightly positive and slightly negative side to each molecule. The positive and negative sides of each water molecule are attracted to other positive and negative sides of other water molecules.

Those ones that are most like water. Like dissolves like.
It dissolves all kinds of molecules. However, the ones that it dissoves well are molecules that it can hydrogen bond with or molecules that are polar that it can have di…pole-dipole interactions with.
Yes, many ionic molecules do dissolve in water by ionization into cations and anions hydrated with (or in) water.
Dissolving is just when water bonds and separates the cation and anion. Water's polarity is the reason why it surrounds each ion and separates it from the oppositely charged …ion thus dissolving it. The negative end of the water surround the positive ion and the positively charged end of water surround the negative ion. If there is a polar molecule it will bond in a network with the polar water molecules This is why water will not dissolve non-polar molecules because the polarity has no affect on a non-polar molecule.
Molecules that are polar dissolve best in water, which is itself highly polar.
A general rule when determining the solubility of one substance into another is to look at their polarity. If both substances are polar they tend to be soluble with each-other…. Water is a polar substance (Oxygen has a higher electronegativity than Hydrogen, therefore it draws the electrons away from the Hydrogen, this combined with the 120 degree H-O-H structure of the molecule causes polarity with the oxygen being slightly negative while the hydrogen atoms are slightly positive). Answer 2 Metals , hydrocarbons , Petroleum , plastics , etc being non polar are insoluble in water .
Hydrophobic liquids like oil will not dissolve in hydrophilic liquids like water. They are "immiscible," meaning they won't form a homogeneous solution if you mix them. In a…ny case, MOLECULES THEMSELVES don't DISSOLVE in water. The ions in ionic compounds like salt become dissociated from each other in water, and they do this more easily in polar (hydrophilic) liquids than they do in hydrophobic ones. But even when a hydrophilic liquid dissolves in water the molecules making up that liquid generally do not.
The molecules soluble in water if they form hydrogen bond with water.Hydrogen bond forms between hydrogen atom and another electro negativity atom of the another molecule then… the substances dissolve in water
This depends on the solubility of these other molecules. Some result in hydrates. If a molecule is dissolved easily in H2O, ions are created; RX R+ + X- and water itself:… H2O H+ + OH-.
The water molecules move around the salt ions In water, the salt separates into positive and negative ions.
